$('input[id^="rad"]').dblclick(function(){
    var nombre = $(this).attr('id');
    var checked =  $(this).is(":checked") ;
    if(checked){
        $("input[id="+nombre+"]:radio").prop( "checked", false );
    }
});

每次双击选中的单选，选中的单选就变为false

我的无线电以id=radxxxxxxxx开头，因为我使用这个id选择器。

Try

$(this).removeAttr('checked')

因为很多浏览器会把'checked=anything'解释为真。这将完全删除checked属性。

希望这能有所帮助。

基于Igor的代码对Laurynas的插件进行了轻微修改。这容纳了与目标单选按钮相关的可能标签:

(function ($) {
    $.fn.uncheckableRadio = function () {

        return this.each(function () {
            var radio = this;
                $('label[for="' + radio.id + '"]').add(radio).mousedown(function () {
                    $(radio).data('wasChecked', radio.checked);
                });

                $('label[for="' + radio.id + '"]').add(radio).click(function () {
                    if ($(radio).data('wasChecked'))
                        radio.checked = false;
                });
           });
    };
})(jQuery);

你不需要each函数

$("input:radio").attr("checked", false);

Or

$("input:radio").removeAttr("checked");

同样也应该适用于你的文本框:

$('#frm input[type="text"]').val("");

但是你可以改进它

$('#frm input:text').val("");

谢谢帕特里克，你让我今天很开心!你必须使用鼠标下键。不过，我已经改进了代码，以便您可以处理一组单选按钮。

//We need to bind click handler as well
//as FF sets button checked after mousedown, but before click
$('input:radio').bind('click mousedown', (function() {
    //Capture radio button status within its handler scope,
    //so we do not use any global vars and every radio button keeps its own status.
    //This required to uncheck them later.
    //We need to store status separately as browser updates checked status before click handler called,
    //so radio button will always be checked.
    var isChecked;

    return function(event) {
        //console.log(event.type + ": " + this.checked);

        if(event.type == 'click') {
            //console.log(isChecked);

            if(isChecked) {
                //Uncheck and update status
                isChecked = this.checked = false;
            } else {
                //Update status
                //Browser will check the button by itself
                isChecked = true;

                //Do something else if radio button selected
                /*
                if(this.value == 'somevalue') {
                    doSomething();
                } else {
                    doSomethingElse();
                }
                */
            }
    } else {
        //Get the right status before browser sets it
        //We need to use onmousedown event here, as it is the only cross-browser compatible event for radio buttons
        isChecked = this.checked;
    }
}})());

使用这个

$("input[name='nameOfYourRadioButton']").attr("checked", false);
